Working with cutting tools and hot plates can be dangerous. In a pinch, you could use a lamp and direct the light with aluminum foil. A "shop light" standing upright works well if you can find a way to keep it upright and steady. This light will be directed into the simulator chamber to light up the vortex, so a "directional" light is better than a lamp that shines light in all directions.Get it shortly before you are about to use it, because it sublimes (turns from a solid to a gas, completely skipping the liquid state) and you will be left with an empty cooler. Have a foam cooler with you when you pick it up, and keep the dry ice in the cooler, not in your freezer or refrigerator. Bigger chunks or blocks are preferable to small "mailing peanut" size cylinders of dry ice. Hospitals use it when they send samples away for analysis, so you can call a hospital lab and ask them their source of dry ice. Ice cream plants use it, so you might be able to get it there. We have heard that some Walmarts have it. Dry ice can be obtained from a number of sources.The more "tracer" you have, the easier it will be to see the vortex. The steam from the boiling water will be the "tracer" that will allow you to see the vortex that forms.You can experiment to see which kind of pan gives you the best results.The higher the wattage, the quicker it will heat the water.Duct tape will be used to connect the pieces of cardboard so that they create a box.However, the duller the finish, the less likely it is to reflect light back and the easier the vortex will be to see. If you don't have paint or dont want to paint, you can use some other black background material that can be secured to the inside of the box. Latex paint dries very quickly and cleans up easily, so that is what we use. The hard kind will make a better window, but is more expensive if you have to buy it. This can be plastic wrap, Saran wrap, clear plastic on a roll, or a sheet of clear, hard plastic.Since that is an odd size, however, we are assuming that you will have to assemble enough cardboard to create one that size. If you can find a 24" high box that is 12" on each side you can cut the bottom and top off and save time.Does it work? Check out this Lyndon State College meteorology alumni with it But this will get anyone who wants to make a model a good start. We will also not go into the "science" of models as the video will. And if you are like us, you will find them both fun to make and mesmerizing to watch.Īlthough we are providing the model plans, we do not intend to supply the extensive directions the video guide to Secrets of the Tornado will have. This simulator is great for science fairs, science projects or reports, or just for fun.
